I contend that the only sensible way to measure freedom (of which privacy is an aspect) is within the context of societal interactions. It's not particularly interesting to move to the middle of nowhere and be able to do do what you want while not interacting with others (what it takes for "on your own [real estate]" to be meaningful). The pertinent metric is how well society can maintain a level of individual liberty (ie tolerance) as it scales up in density of interactions.
And nobody said anything about wanting to be unaccountable for harm. Rather it's a matter of being vulnerable to ne'er do wells. When we get a US GDPR equivalent with teeth, develop a widespread societal taboo against the surveillance industries, and so on, then we can talk about an equitable tradeoff with accountability for harm. Until then, the dynamic is an overwhelming vulnerability.
That analysis seems pretty confused to me. Freedom without accountability for harm to others is nonsensical.
As is dramatizing license plates as "overwhelming vulnerability". Just look at the US's 40k traffic deaths per year, with countless lesser injuries and accidents. Balanced against which specific harms of license plates?
The problem with Flock, etc, is their massive, unaccountable, for profit surveillance, which uses much more than license plates, and is working hard to move beyond them.
